The Last Ascent

The Last Ascent


The wind cut harder the higher we went, needling exposed skin, clawing at the loose edges of coats. My hands were stiff now, fingers refusing to curl properly around the metal rungs, but I didn’t dare loosen my grip. Every movement had to be deliberate. Below, the tower’s skeleton swayed just enough to remind me how far we were from anything solid.

The frame vibrated—not just from the wind, but from the rhythm of pursuit. That steady, mechanical cadence. The mech’s climb wasn’t graceful, but it was relentless.

Vale kept the lead, movements sure and economical, as if the climb cost him nothing. Tessa followed close behind, her jaw set, eyes locked upward. Leigh came next, breathing hard but never pausing. I brought up the rear, the hum of adrenaline in my skull mixing with the distant grind of gears and servos.

Every so often I risked a glance down. Through the web of beams, I could see the thing’s silhouette pulling itself higher, metal limbs gripping the framework like an insect’s. The glow from its visor slit washed over the steel around it in brief, slicing arcs.

The haze thickened again, swallowing the edges of the world. I lost sight of the ground entirely—there was only the black void below and the pale blur above. My shoulders screamed from the climb, but I didn’t slow.

“Almost there,” Vale called over his shoulder.

The next platform was unlike the others. It wasn’t just a landing—it was an enclosed deck with high walls of bolted sheet metal, the roof formed from a patchwork of scavenged panels. The air inside smelled faintly of ozone and oil, warmer than it had any right to be this high up.

Vale pulled himself over the edge first, scanning quickly before helping the rest of us up. Once my boots hit the deck, my knees nearly gave.

The space was dominated by a central structure—a narrow control column, cables feeding into it from every direction, its front studded with switches and cracked display screens. Beside it stood a tall, narrow cylinder strapped upright against the wall, painted a deep red and stenciled with warning glyphs.

Leigh’s eyes locked on it instantly. “That’s a fuel cell,” she breathed.

Tessa’s gaze flicked from the cell to the control column. “For what?”

Vale didn’t answer immediately. He was already at the column, brushing dust from one of the displays. The screen flickered to life under his touch, filling with green-tinted schematics—maps of the district, each overlaid with shifting data points.

“It’s a hub,” he said finally. “For the whole sector.”

The mech’s climb echoed closer.

“We can’t stay here,” Tessa said.

“No,” Vale agreed. “But we can end it here.”

Leigh stepped forward. “You’re thinking of overloading it.”

“I’m not thinking,” he said. “I’m certain.”

The platform shuddered—whether from the wind or the mech’s approach, I couldn’t tell. The sound of steel on steel scraped up the tower’s spine.

Leigh’s voice sharpened. “You overload that cell without a controlled bleed, you’ll take half the block with it.”

“That’s the idea,” Vale said, without looking at her.

The words landed like a punch. My throat tightened. “We’re still in the block.”

Vale turned then, meeting my eyes with a steadiness that was almost worse than anger. “You think it’s coming for just us? This thing’s here to clear everything that’s left. If we go, we take it with us.”

Tessa’s gaze slid to the opening in the far wall, where the exterior stairs continued upward into the haze. “What’s at the very top?”

“Transmission mast,” Vale said. “If the signal’s still live, it’s feeding straight through here. If we cut it, maybe we scramble their network before the blast.”

The mech’s head rose into view through the gaps in the wall—closer now, visor glow slicing the dim. The sound of its climb became deafening, each impact shaking the floor under our feet.

Vale’s voice dropped to a clipped growl. “Tessa—mast. Eliza—help Leigh with the bleed. I’ll hold it here as long as I can.”

There was no time to argue. Tessa was already moving toward the far stairs, her boots ringing against the steel. Vale turned toward the opening, drawing the compact weapon from his pack—a short, brutal thing that looked like it had been assembled from scrap but carried a weight that made my stomach twist.

Leigh pulled me toward the control column, yanking open a side panel to reveal a mess of wires and exposed couplings. The heat rolling off them made the air shimmer.

“Here,” she said, shoving a small insulated tool into my hand. “You’re going to hold the relay open while I kill the feed. When I say now, you do not hesitate.”

I nodded, my palms slick despite the cold.

The mech’s hand gripped the platform’s edge, fingers curling over the steel with a screech. Vale fired, the report rattling in my bones. Sparks showered from the mech’s forearm, but it didn’t let go—it just pulled itself higher.

“Now!” Leigh barked.

I jammed the tool into the relay, holding it steady as she wrenched a heavy cable free. The lights in the column flickered, then steadied again, this time with a deeper hum.

“That’s the bleed,” she said, breath quick. “Now we have a timer.”

“How long?”

“Minutes if we’re lucky.”

Vale fired again, the round punching into the mech’s torso with a clang that echoed through the enclosure. The machine staggered back half a step, then surged forward, one arm snapping out toward him.

He ducked, rolling to the side, and came up firing again—point blank this time. The mech reeled, its visor light flaring, but it didn’t fall.

Tessa’s voice crackled through the comm unit clipped to Leigh’s coat. “Mast’s down. Repeat—mast’s down.”

Vale didn’t look away from the mech. “Then we’re done here. Go!”

Leigh yanked the tool from my grip and shoved it into her pocket, then grabbed my wrist. We sprinted for the far stairs, Vale falling back step by step as he kept firing. The mech lunged, tearing a section of the wall open like paper, but Vale slipped past the gap and slammed a beam down across the opening, buying us seconds.

We climbed again, the fuel cell’s hum now a low, insistent growl beneath our feet. The stairs shook as the mech forced its way onto the platform below.

By the time we reached the upper deck, the haze had thinned just enough to show the broken skyline. Tessa stood at the railing, wind tearing her hair across her face, watching the district’s distant edge where faint lights still flickered.

Vale burst up behind us, slamming the hatch shut and jamming another beam through the latch. “That won’t hold it long.”

Leigh’s eyes swept the deck. “We jump from here, we might clear the blast radius.”

“Might,” Vale said flatly.

I stepped to the edge, looking down. The ground was so far below it felt unreal, like a painted backdrop. The only thing between us and it was air—and the skeletal remains of the buildings that had once filled this part of the city.

The mech’s pounding reached the hatch. Metal screamed.

Vale’s voice cut through the wind. “We jump on my mark. Tessa, you take point. Eliza, you follow. Leigh, last. I’ll be right behind.”

“What if you’re not?” I asked before I could stop myself.

His eyes held mine for half a heartbeat. “Then you run.”

The hatch tore open.

The mech rose through the gap, smoke curling from the rents in its plating, visor light burning like a blade in the dim.

Vale didn’t hesitate. “Mark!”

Tessa vaulted the railing, dropping into the void. I went next, the wind punching the breath from my lungs as the world spun in a blur of grey and black.

Somewhere above, the fuel cell’s hum climbed into a shriek.
